Most users are familiar with Bejeweled, the classic puzzle game that requires you to line up jewels of the same color in order to eliminate them from the grid.
Bejeweled 2 is a free browser game that works on exactly the same principle. You don't need to register, so getting started is as simple as clicking on a few buttons. There are 2 game modes - classic and action. Action requires you to clear a certain number of jewels before time runs out, while classic takes a more relaxed approach.
This webapp has some basic options, and is supported by ads. This means that you'll see an ad before each new level starts, which can be a bit annoying. When playing Bejeweled 2, you can choose to turn on or off the sound and access some basic help - although as this is a pretty basic game, you probably won't need any.
For a free, easy game, Bejeweled 2 will definitely keep you entertained. The ads are a little irritating though, and the game backgrounds are strangely ugly!
Classic puzzle fans will get a kick out of Bejeweled 2.
